The invention relates to shade holders and particularly to those employed for supporting shades of bridge lamps in functional position, although the invention may be generally employed where a shade is to be supported.

In mounting a shade, it has been custom-y ary to provide a holder ring which 1s pro` this construction are that thecost of mount-v ing the shade is rather high and that the assembly is not rigid, permitting a certain play of the shade under the influence of jars or shocks.

Itis, therefore, an object of the invention to provide a shade holder ring adapted to be 'rigidly secured to the shade so as to preclude swaying of the shade under the in-V fluence of jars. I Another object aims at the pro-vision of a holder ring which is sturdy and may be cheaply connected with the shade.

With these and other objects in view which will become apparent upon perusal of the invention, the latter comprises the meansV set forth in the :following` specification, particularly pointed out in the claims forming a part thereof,rand illustrated in the accompanying drawings, in which n Figure 1 is an elevational view of a bridge lamp;

Figure 2 is a top plan view of a shade 1n Whichthe invention is incorporated;

Figure 3 is an enlarged bottom plan view of a shade ring holder;

Figure 4 is a section on the line 4 4 of Figure 3; and Y n Figure 5 is a sectional elevation of a well-known ring holder.

Referring to the several views in the drawing, 10 generally designates a bridge lamp comprising a base 11, a` post 12, an arm or bracket 13 from which a socket 14 is suspended, and a shade 15 surrounding the socket and its bulb. In order to hold the shade in proper position, a flat ring 16 is provided which is .formed with a circular depending flange 17 at right angles to the ring andl surrounding the central aperture 18. The inner surface of the Vange is formed with screw threads 19 adapted to be threadedly and rigidly secured to the lamp socket as will be readily understood by those versed in the art. The ring is formed with a plurality of flat lugs or extensions 20 which extend outwardly in the same plane as the ring proper and are formed integral therewith. In the present instance tour lugs are provided, but a larger or lesser'numberl may be employed if so desired.

The shade 15 includes an upper shade-supporting wire ring 21 and a'lower wire ring `22which are connected by brace wires` 23.

From the upper ring aI plurality of wires 24 extend toward the center and their inner ends are brazed to the lower sides of the corresponding lugs 20 of the holder ring, said wires, lugs, wire ring 21 and holder ring be ing formed kto lie in approximately the same plane in order to permit of easier manufacture and assemblage of the parts than in the usual construction.

Thus it will be seen that the holder ring 16 is of simple and practical construction, and the. ends of wires 24 are quickly secured to the ring by brazing.

In Figure 5 the known manner of securing the shadeto the holder ring is illustrated. kHere the ring 25 comprises a threaded sleevev 26 constituting `a circular flange at the central aperture of the ring body 26. The latter-is bent downwardly yand provided with a plurality of apertures 27 through which the wires 24 are introduced and curled around the-freeiedge of the ring body.

It is obvious that the known ring holder is of more expensive construction, and more costly in assembling the shade than the new holder ring, which is marked by simplicity, strength of material and ease in assembling the shade.

While the invention is illustrated in conneet-ion with a brid e lamp, its application is nevertheless not limited thereto, but may be extended to all cases wherever a shade is to be supported. v

The details of construction are also shown merely by way of example and not by way of limitation.

I, therefore, do not limit myself to any v partures Within the scope of theinvention as defined in the appended claim.m

l. claim: l 1

The combination with a shade supportino wire ring of a Hat metal ring provided Wit 1 a plurality of integral flat extensions at its circumference and in the same plane: a plurality of Wires secured to said Wire ring and brazed to the underside of Vsaid extensions,

said Wire ring, Wires and fiat ring being l0 formed to be substantially in the same plane, and a depending circular and' threaded flange at the central aperture of said flat ring and normal thereto and adapted to screw7 over a lamp socket;y

In Witness whereof I affix-my signature.

LAWRENCE H. LEVINSON.
